The Speedmaster 1-148-051-02 is a two-piece fabricated ram air intake manifold engineered specifically for Chevy LS3 applications. Featuring a large 98mm throttle body bore with a 4-bolt flange, this EFI-ready manifold is designed to maximize airflow and support serious power gains over restrictive stock units. The aggressive ram air design helps force a denser air charge into the engine for improved throttle response and top-end performance.
Finished in a sleek black coating, this intake manifold delivers a clean, purposeful look under the hood while standing up to the heat and demands of high-performance use. The two-piece fabricated construction allows for precise fitment on LS3 engines, making it a strong choice for street builds, track cars, or engine swaps where a high-flow EFI intake is needed. Designed and backed by Speedmaster, a trusted name in performance engine components.
